Question

a car is moving with a velocity of u and covers a distance of 800m with an acceleration of 6m/s .calculate velocity in 10 sec and also find the value of u​

Answer 1

Answer:

u=50m/s

v=110m/s

Explanation:

S=ut+1/2at^2

800=10u+1/2x6x100

800=10u+600/2

800-300=10u

500=10u

u=50m/s

v=u+at

=50+6×10

=110m/s
